Our Work

Our research covers four areas: Teaching and Learning
Powerful Ideas, Powerful Ideas Content and How to Represent
It, User Interfaces that Aid Learning and Doing, and Inventing
Fundamental New Computing Technologies.

We want to start with the teaching and learning
of old and new "powerful ideas"; create much better human-computer
environments that allow for authoring, sharing and representing
the new ideas; create new user-interfaces that can help children
and adults "learn and do" the new ideas; and, invent new, fundamental
computing technologies to serve as the raw material for the
next stage of the computer revolution. We build everything we
invent and we engineer our prototypes for the greatest usability.
Both of our recent free and open source software prototypes,
Squeak Etoys
and Croquet
have gone out successfully to tens of thousands of users.
